PTFE ultrafiltration membrane is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene.

Ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, small molecular solutes and solvents are allowed to pass through a special membrane with a certain pore size, while large molecular solutes cannot pass through and remain on one side of the membrane. , thereby partially purifying macromolecular substances.

The principle of ultrafiltration is also a membrane separation process principle. Ultrafiltration uses a pressure-active membrane to intercept colloids, particles and substances with relatively high molecular weight in the water under the action of external driving force (pressure), while water and small The process of separation of solute particles through a membrane.

Substances with a molecular weight of 3×10000-1×10000 can be screened through the micropores on the membrane surface.

When the water to be treated passes through the membrane surface at a certain flow rate with the help of external pressure, water molecules and solutes with a molecular weight less than 300-500 pass through the membrane, while particles and macromolecules larger than the membrane pores are due to the sieving effect. is trapped, thereby purifying the water.

In other words, when water passes through the PTFE ultrafiltration membrane, most of the colloidal silica contained in the water can be removed, and a large amount of organic matter can be removed at the same time.

The treatment process has no phase change and has no adverse effects on the components of the material. The separation, purification, and concentration processes are always at room temperature. It is especially suitable for the treatment of heat-sensitive substances and completely avoids the destruction of biologically active substances by high temperatures. One disadvantage is that it effectively retains the biologically active substances and nutrients in the raw material system.

It is a ptfe ultrafiltration membrane manufacturer specializing in R&D, production and sales.

We have a complete service system, with thoughtfulness before sales, attentiveness during sales, and peace of mind after sales! You are welcome to come to the company for inspection or enter the store to consult us at any time.
